Extremy hard to find these days. This is probably the most lush and thick sounding chorus I've heard / used for bass and guitar. Due to the discontinued and hard to find chips that are used in the vintage chorus pedals it is hard for any of the newer pedals to cop the same mojo - the digital chorus pedals out there steal low end frequencies. Check out my video below to hear this in action.

This is a used DOD FX64 Ice Box Chorus cosmetically in good condition and is fully functional. No power supply or battery. Will run off a 9v adapter or 9v battery.
